In our ongoing efforts aimed at improving the listening skills of people new to classical music, we come to instrumentation. It is helpful in learning to understand a particular piece to be able to identify, just with your ears, which instruments are playing when and what. Putting mental labels on sounds is an aid to our brains in sorting things out.

There are two melodies in Ravel’s “Bolero,” each played twice before alternating with the other. The piece is basically one long crescendo in C, and Ravel sets the melodies in a variety of solo instruments, and then groups of instruments.

For the sound file below (which features a performance of “Bolero” performed by the London Symphony Orchestra, conducted by Claudio Abbado), we have added the timings for the entrance of every appearance of the melodies, and the instrument(s) that Ravel has decided will play them. (Later in the piece, when Ravel has large groups of instruments play the melodies, it is difficult to aurally distinguish every single instrument, but you can hear changes in the overall tone color.)
